Description

Technical Field

[0002] In modern industrial production processes, especially in the manufacturing of plastic products, the use of plastic bonding resins has become crucial. As a special chemical material, plastic bonding resins are widely used in the bonding of various plastic parts to improve the overall performance and service life of the products. However, with the increasing demand for high-quality plastic bonding resins, the shortcomings of traditional production equipment in production efficiency and product consistency have become increasingly apparent, among which the problem of low mixing efficiency is particularly prominent.

[0003] Existing plastic adhesive resin production equipment usually uses mechanical stirring to promote the mixing and uniform dispersion of reaction materials. However, due to the limitations of equipment design, these devices are difficult to achieve uniform mixing of all materials during the stirring process, resulting in instability in resin quality. Traditional stirring equipment is limited by the design of the stirring paddle and the shape of the stirring container, resulting in the generation of mixing dead corners. These dead corners prevent some materials from fully participating in the mixing process, thereby affecting the chemical and physical properties of the final product.

[0004] In order to improve production efficiency and product quality, many processes need to rely on complex and time-consuming auxiliary equipment to make up for the shortcomings of the mixing process, such as introducing multiple mixing steps or using different types of mixing devices.

[0025] 2. Optimize production efficiency: Add a linkage structure between the cooling component and the screen plate to break up and cool the fully mixed materials in time, which can prevent the raw materials from forming high-temperature aggregation during the mixing process and avoid quality loss due to thermal degradation, thereby ensuring the uniform distribution of the resin components.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, an embodiment of the present invention provides a production device for plastic adhesive resin, including a plurality of stirring rods 3 arranged on the surface of a stirring shaft 2, a processing box 4 connected to the discharge port of a stirring tank 1, a processing mechanism arranged in the processing box 4 for cooling and screening the falling materials; a plurality of stirring mechanisms 5 are arranged on the inner side wall of the stirring tank 1, the stirring mechanisms 5 are slidably connected to the inner wall of the stirring tank 1, and the stirring mechanisms 5 can move horizontally toward the middle of the stirring tank 1;

[0039] A flow guide pipe 6 is arranged around the outer circumference of the stirring tank 1. The inner end surface of the flow guide pipe 6 is connected to the corresponding position of each stirring mechanism 5 with a connecting pipe 7. The other end of the connecting pipe 7 is connected to the outer wall of the stirring tank 1. Each stirring mechanism 5 extends through and is connected to the corresponding connecting pipe 7. An inlet valve and an outlet valve are respectively arranged at both ends of the flow guide pipe 6 to input high-pressure fluid into the flow guide pipe 6. The high-pressure fluid is used to push the stirring mechanism 5 to move horizontally. When the high-pressure fluid flows out of the flow guide pipe 6, the stirring mechanism 5 is reset and re-contacted with the inner wall of the stirring tank 1. When the stirring mechanism 5 moves horizontally, it can drive the material at the inner edge of the stirring tank 1 to flow to the middle.

[0040] See also Figures 5 to 8 As shown, three agitating mechanisms 5 are arranged at equal intervals on the inner side wall of the mixing tank 1, and each agitating mechanism 5 includes a push plate 51, a connecting rod 52, a sealing block 53 and a return spring 54. The sealing block 53 is arranged inside the connecting pipe 7 and slides against the inner wall of the connecting pipe 7. One end of the connecting rod 52 is connected to the inner end surface of the sealing block 53, and the other end of the connecting rod 52 passes through the side wall of the mixing tank 1 and extends to the inside thereof, and the end is connected to the push plate 51. A return spring 54 is connected between the inner end surface of the sealing block 53 and the outer wall of the mixing tank 1. A plurality of limiting openings 55 are provided on the left and right sides of the inner end surface of the push plate 51, and a rotating shaft is vertically arranged in each limiting opening 55. Agitating plates 56 are arranged on the left and right sides of the push plate 51, and the agitating plates 56 are connected to the rotating shaft on the same side, so that they can rotate at an angle of up to 90° along the rotating shaft.

[0041] When a high-pressure fluid (such as gas or liquid) is introduced into the flow guide tube 6, as the high-pressure fluid flows into the connecting tube 7 and continues to flow in, the high-pressure fluid will push the sealing block 53 to move out of the connecting tube 7, thereby driving the push plate 51 in the mixing tank 1 to move toward the middle through the connecting rod 52;

[0042] Through the design of the limit opening 55, when the connecting rod 52 extends toward the middle of the stirring shaft 2, the agitator plates 56 on both sides of the push plate 51 will automatically expand to the side as the connecting rod 52 extends due to the material resistance, thereby effectively increasing the pushing area of ​​the push plate 51 through the opened agitator plates 56, so that the push plate 51 can push a large amount of material to flow toward the middle when it extends once; and when the connecting rod 52 retracts, the agitator plates 56 will be affected by the material resistance behind them and turn back to a state perpendicular to the push plate 51, thereby preventing the agitator plates 56 from pushing the material flowing to the middle back to the edge when the connecting rod 52 retracts.

[0043] See also Figures 6 to 8 As shown, a mixing drum 11 is provided inside the mixing tank 1, and a mixing shaft 2 is provided in the mixing drum 11. A cavity is left between the outer wall of the mixing drum 11 and the inner wall of the mixing tank 1. The inner wall of the mixing tank 1 connected with each connecting pipe 7 is rotatably connected with a sleeve 57, and the sleeve 57 is sleeved on the surface of the connecting rod 52. The surface of the connecting rod 52 is provided with a plurality of grooves 58 at equal intervals along the length direction. The inner wall of the sleeve 57 is provided with a plurality of clips that are slidably engaged with each groove 58 respectively. The connecting rod 52 is rotatably connected to the inner end surface of the sealing block 53. A driving device is provided in the cavity. The driving device is used to drive each sleeve 57 to rotate, so as to drive the connecting rod 52 to rotate synchronously through the engagement of the clips with the grooves 58.

[0044] See 4 and Fig. 9 As shown, the driving device includes a rotating ring 12 and a conical gear ring 13 arranged on the rotating ring 12, the rotating ring 12 is rotatably connected to the inner wall of the mixing tank 1, and the surface of each sleeve 57 is sleeved with a bevel gear 59, which is meshed and connected with the conical gear ring 13. The outer wall of the mixing tank 1 is provided with a second motor 14, and the output shaft of the second motor 14 extends through and is transmission-connected with the conical gear ring 13; the surface of the mixing shaft 2 is surrounded by three rows of mixing rods 3 groups along its own axis, and each row of the mixing rods 3 groups is composed of a plurality of mixing rods 3 arranged along the length direction of the mixing shaft 2, and the interval between the middle parts of two mixing rods 3 on the same horizontal plane of two adjacent rows of mixing rods 3 groups is greater than the length of the push plate 51, and this size design can ensure that the push plate 51 will not collide with the mixing rod 3 when rotating;

[0045] The conical gear ring 13 is driven to rotate by the second motor 14, thereby linking the meshing bevel gears 59 thereon to rotate, and in turn driving the connecting rod 52 and the push plate 51 thereon to rotate synchronously. The push plate 51 rotates on the vertical plane, and can form stirring flows in different directions relative to the stirring shaft 2 rotating on the horizontal plane. By regularly changing the stirring direction, the material distribution in the dead corner area can be effectively broken, and the overall mixing effect is promoted. In addition, by matching the different amounts of high-pressure fluid introduced into the guide tube 6, the extension distance of the connecting rod 52 can be controlled, so that the push plate 51 can be controlled to rotate on different vertical planes, which can ensure that the stratification of raw materials and the occurrence of stirring dead corners can be effectively avoided.

[0046] See 4 and Figure 5 As shown, a heating tube 15 is spirally wound on the outer surface of the mixing drum 11, and the heating tube 15 is connected to an external heat source for inputting a high-temperature fluid therein. The high-temperature fluid flows in the heating tube 15, thereby transferring its own heat to the mixing drum 11 by means of heat transfer, thereby heating the mixing drum 11 to heat the material therein and improve the high-temperature reaction conditions; and.

[0047] See also Figure 2 and Figure 3 As shown, the processing mechanism includes a cooling assembly 8 and a sieve plate 9 located below the cooling assembly 8, the cooling assembly 8 includes a first frame 81 and a second frame 82, the first frame 81 and the second frame 82 are respectively embedded with a first water pipe 83 and a second water pipe 84, and the first water pipe 83 and the second water pipe 84 are both continuous S-shaped structures and are respectively assembled in the first frame 81 and the second frame 82, the left and right ends of the processing box 4 are respectively installed with a shunt pipe 85 and a return pipe 86, the first water pipe 83 and the second water pipe 84 are respectively connected to the shunt pipe 85 and the return pipe 86, the shunt pipe 85 is connected to an external water source for inputting cooling water, and the return pipe 86 is connected to an external heat source for recovering cooling water;

[0048] When the mixture contacts the first water pipe 83 and the second water pipe 84, it transfers its own heat to the surface of the first water pipe 83 and the second water pipe 84, and then the cooling water flowing in the first water pipe 83 and the second water pipe 84 absorbs the heat, thereby achieving the effect of cooling. The cooling water that has absorbed the heat has its own temperature increased, and only needs to be simply heated before it can be passed into the heating pipe 15 to improve the heating conditions for the subsequent raw material stirring. In this way, the heat of the mixture can be effectively recycled and utilized, saving energy consumption costs.

[0049] See 3 and Figure 6As shown, the right end of the processing box 4 is equipped with a cylinder 87, and the piston rod of the cylinder 87 penetrates and is connected to the first frame 81. The front and rear sides of the first frame 81 are slidably connected to the inner wall of the processing box 4 through slide rails 88, and the cylinder 87 is used to drive the first frame 81 to make horizontal reciprocating motion. The bottoms of the front and rear sides of the first frame 81 are hingedly connected with a plurality of connecting frames 89, and the other end of the connecting frame 89 is hingedly connected to the top of the same side of the second frame 82, and a key hole 90 is opened in the middle of the connecting frame 89. The front and rear sides of the inner wall of the processing box 4 are provided with a plurality of limit blocks 91 located in each corresponding key hole 90. When the first frame 81 makes horizontal reciprocating motion, it will drive the second frame 82 below it to move synchronously and staggeredly through the connecting frame 89. The two ends of the first water pipe 83 and the second water pipe 84 are respectively connected to the shunt pipe 85 and the return pipe 86 through a hose 92;

[0050] By continuously moving the first frame 81 and the second frame 82 back and forth and staggered, the mixture discharged into the processing box 4 will not fall into one place, but will fall evenly on various places of the first water pipe 83 and the second water pipe 84, effectively utilizing the surface area of ​​the first water pipe 83 and the second water pipe 84, thereby improving the cooling effect. At the same time, the first frame 81 and the second frame 82 continuously move, and can also break up the fallen mixture so that it can fall onto the screen plate 9 in a dispersed manner, thereby also improving the screening efficiency.

[0051] See 3 and Figure 6 As shown, the bottom ends of each corner of the sieve plate 9 are connected to the inner wall of the processing box 4 through springs 93, and at least one arc-shaped pressure block 94 is arranged on the top ends of the front and rear sides of the sieve plate 9. The bottom ends of the front and rear sides of the second frame 82 are arranged with arc-shaped top blocks 95 corresponding to the pressure blocks 94 on the corresponding side. The top blocks 95 are in contact with the pressure blocks 94. Therefore, when the second frame 82 is driven to move by the first frame 81, due to the arc structure of the top blocks 95 and the pressure blocks 94, when the top blocks 95 move from one side of the pressure blocks 94 to the other side, the pressure blocks 94 will be pressed down, thereby driving the sieve plate 9 thereon to vibrate, so as to improve the screening efficiency of the mixture; a cleaning port is provided at the front end of the processing box 4, and the cleaning port is connected to the top of the sieve plate 9 for cleaning the materials remaining on the sieve plate 9.

[0052] Another object of the present invention is to provide a production process of plastic adhesive resin, which is applied to the above-mentioned production equipment and includes the following steps:

[0053] S1, primary mixing: various weighed raw materials are put into a stirring tank 1, and the raw materials are stirred and mixed at high speed by a stirring shaft 2 under heating conditions to form a mixture;

[0054] S2, secondary mixing: after the stirring shaft 2 stirs at high speed for a period of time, it stops rotating and stops at a suitable position. At this time, a high-pressure fluid is introduced into the flow guide pipe 6, and the high-pressure fluid drives the push plate 51 to move toward the middle of the stirring tank 1, thereby driving the mixture located on the side to flow to the middle. The push plate 51 moves back and forth to change the material distribution in the dead corner area of ​​the stirring tank 1. After the push plate 51 is reset, the stirring shaft 2 continues stirring. The above steps are repeated for multiple times to finally form a uniformly mixed mixture;

[0055] S3, preliminary cooling: after the mixing is completed, the mixture is discharged from the stirring tank 1 into the processing box 4, and the mixture is rapidly cooled when passing through the processing mechanism to reduce the temperature of the mixture, prevent the resin from continuing to react and decompose due to overheating, and ensure that the temperature is reduced to a safe range for subsequent processes;

[0056] S4, screening: the mixture after preliminary cooling continues to be screened in the processing mechanism to remove large particles or impurities that may exist in the mixture. Impurities or incompletely dissolved materials may affect the performance of the final product. Screening can remove these problems to ensure the purity and uniformity of the adhesive resin, and ensure the smoothness and bonding effect of the resin. Finally, the screened resin is discharged and collected from the bottom of the processing box 4. Embodiment 2

[0057] The difference between this embodiment and embodiment 1 is: Figures 6 to 8 As shown, a mixing drum 11 is provided inside the mixing tank 1, and a mixing shaft 2 is provided in the mixing drum 11. A cavity is left between the outer wall of the mixing drum 11 and the inner wall of the mixing tank 1. The inner wall of the mixing tank 1 connected with each connecting pipe 7 is rotatably connected with a sleeve 57, and the sleeve 57 is sleeved on the surface of the connecting rod 52. The surface of the connecting rod 52 is provided with a plurality of grooves 58 at equal intervals along the length direction. The inner wall of the sleeve 57 is provided with a plurality of clips that are slidably engaged with each groove 58 respectively. The connecting rod 52 is rotatably connected to the inner end surface of the sealing block 53. A driving device is provided in the cavity. The driving device is used to drive each sleeve 57 to rotate, so as to drive the connecting rod 52 to rotate synchronously through the engagement of the clips with the grooves 58.

[0058] See 4 and Fig. 9As shown, the driving device includes a rotating ring 12 and a conical gear ring 13 arranged on the rotating ring 12, the rotating ring 12 is rotatably connected to the inner wall of the mixing tank 1, and the surface of each sleeve 57 is sleeved with a bevel gear 59, which is meshed and connected with the conical gear ring 13. The outer wall of the mixing tank 1 is provided with a second motor 14, and the output shaft of the second motor 14 extends through and is transmission-connected with the conical gear ring 13; the surface of the mixing shaft 2 is surrounded by three rows of mixing rods 3 groups along its own axis, and each row of the mixing rods 3 groups is composed of a plurality of mixing rods 3 arranged along the length direction of the mixing shaft 2, and the interval between the middle parts of two mixing rods 3 on the same horizontal plane of two adjacent rows of mixing rods 3 groups is greater than the length of the push plate 51, and this size design can ensure that the push plate 51 will not collide with the mixing rod 3 when rotating;

[0059] The conical gear ring 13 is driven to rotate by the second motor 14, thereby linking the meshing bevel gears 59 thereon to rotate, and in turn driving the connecting rod 52 and the push plate 51 thereon to rotate synchronously. The push plate 51 rotates on the vertical plane, and can form stirring flows in different directions relative to the stirring shaft 2 rotating on the horizontal plane. By regularly changing the stirring direction, the material distribution in the dead corner area can be effectively broken, and the overall mixing effect is promoted. In addition, by matching the different amounts of high-pressure fluid introduced into the guide tube 6, the extension distance of the connecting rod 52 can be controlled, so that the push plate 51 can be controlled to rotate on different vertical planes, which can ensure that the stratification of raw materials and the occurrence of stirring dead corners can be effectively avoided.

[0060] The difference from Example 1 also includes: in step S2 of its production process, when the push plate 51 is extended under the drive of high-pressure fluid, the second motor 14 drives the conical ring gear 13 to rotate, and drives the sleeve 57 to rotate synchronously through the bevel gear 59, thereby driving the connecting rod 52 and the push plate 51 thereon to rotate, so that the material can flow in multiple directions in the mixing drum 11, forming a more complex flow path, thereby reducing the formation of dead angles.

[0061] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
